Abstract: The main product of the reaction system NaVO3-Ca(NO3)2-HNO3-H2O at 20-60° was Ca3V10O28.xH2O (x = 16-17). In pure state it can be prepd. at 20° and 40° only. For lower acidification degrees it was contaminated by Ca(VO3)2.4H2O and for higher values of acidification by a brown substance. The main component of the brown product was Na2V6O16.3H2O or NaHV6O16.xH2O. A new double vanadate(V) of the compn. Na4CaV10O28.19H2O was prepd.
